summary: Telnet command for showing TLS info
...
Introduction
============
This module adds two commands to the telnet console, `c2s:showtls()` and
`s2s:showtls()`. These commands shows TLS parameters, such as ciphers
and key agreement protocols, of all c2s or s2s connections.
Configuration
=============
Just add the module to the `modules_enabled` list. There is no other
configuration.
modules_enabled = {
...
"telnet_tlsinfo";
}
Usage
=====
Simply type `c2s:showtls()` to show client connections or
`s2s:showtls()` for server-to-server connections. These commands can
also take a JID for limiting output to matching users or servers.
s2s:showtls("prosody.im")
